The LTC5505-X is an RF Power detector for RF applications operating in the 300MHz to 3.5GHz range. A temperature compensated SchottkyDiode peak detector and BufferAmplifier are combined in a small 5-pin ThinSOT package. The supply voltage range is optimized for operation from a single lithium-ion cell or 3xNiMH.The RF input voltage is peak detected using an on-chip SchottkyDiode The detected voltage is buffered and supplied to the VOUT pin. A power saving shutdown mode reduces supply current to less than 2A.The LTC5505-1 operates with input power levels from 28dBm to 18dBm. The LTC5505-2 operates with input power levels from 32dBm to 12dBm. By Linear Technology Corporation
